Explanation:

Ratio of men : women : children = 9 : 8 : 3
Suppose, Men = 90, Women = 80, Children = 30
Total population = 200
Now, No. of literate men = 90 x 80 /100 = 72 ......(i)
No. of literate women = 80 x 70 /100 = 56 .........(ii)
No. of literate children = 30 x 90 /100 = 27. .........(iii)
Total no. of literate person = 155
No. of illiterate people 200 – 155 = 45
So, illiteracy rate = 45/200 x 100 = 22 1/2%
